The Wastewater Treatment Division is responsible for the proper treatment of the City's domestic and commercial sewage.
The current staffing level in this division is 9 personnel. The collection system consists of 145+ miles of gravity and force main sewer pipelines. The pipelines are composed of a mixture of clay and ductile iron pipe, ranging in size from 2 to 36 inches. Age of the sewer pipelines range from new to more than 50 years old. Collection is accomplished by gravity from homes and businesses until it is necessary to pump from low elevations in force main sewer lines that transport the sewage to the treatment plants. There are 20 pump stations in the collection system. These range in size from pumping a few thousand gallons per day to more than five million gallons a day (MGD). All of the city sewer drains, collects or is pumped to the Mebane Bridge Wastewater Treatment Plant (MBWWTP), which can treat 13.5 million gallons per day.
